Abstract
Articles that include water-soluble films and household care composition, where the films include a polyvinyl alcohol (PVOH) resin blend and optionally one or more additional components such as plasticizers, fillers, surfactants, and other additives. The PVOH resin blend includes a PVOH copolymer including one or more types of anionic monomer units such as a PVOH terpolymer and a PVOH polymer such as another PVOH anionic copolymer or a partially or completely hydrolyzed PVOH homopolymer. When the PVOH copolymer and PVOH polymer are blended in particular proportions and/or selected with regard to various criteria related to physical and chemical film properties, the resulting water-soluble film formed from the PVOH resin blend exhibits substantially improved aqueous dissolution properties, tensile strength properties, and/or tensile modulus properties.
